The hypoglycemic effects of four edible plants (Angelicae tenuissimae (A. ten.), Pleurospermum kamtschaticum (P. kam.), Adenophora remotiflora (A. rem.) and Zanthoxylum schinifolium (Z. sch.)) in streptozotocin (STZ) -induced diabetic rats were investigated. Sprague-Dawley male rats weighing 190-230 g were induced diabetes mellitus by the STZ injection (45 mg/kg) into the tail vein and were divided into six groups ; normal, STZ-control and four edible plant groups (A. ten., P kam., A. rem. and Z. sch. groups). Normal and STZ-control groups were fed a AIN-93 diet and four groups of STZ-induced diabetic rats were fed one of each experimental diets containing 10％ of the edible plant powder for 4 weeks. Diabetic rats showed the lower weight gain compared to the normal rats. In experimental groups except P. kam., AST activities were close to normal. A. ten. group were lowered ALT activities slightly. The plasma glucose levels of the diabetic experimental groups were significantly decreased at 4th week. The plasma insulin levels in diabetic experimental groups were not significantly different compared to the STZ-control group. The liver glycogen levels in STZ injected rats were significantly lower in compared to the normal rats. However no significant differences were found in response experimental plants intake in diabetic rats. The muscle glycogen were not significantly different among all the groups.

Esophageal candidiasis is commonly seen in immunocompromised patients; however, candida esophagitis induced stricture is a very rare complication. We report the first case of esophageal stricture secondary to candidiasis in a glycogen storage disease (GSD) 1b child. The patient was diagnosed with GSD type 1b by liver biopsy. No mutation was found in the G6PC gene, but SLC37A4 gene sequencing revealed a compound heterozygous mutation (p.R28H and p.W107X, which was a novel mutation). The patient's absolute neutrophil count was continuously under $1,000/{\mu}L$ when he was over 6 years of age. He was admitted frequently for recurrent fever and infection, and frequently received intravenous antibiotics, antifungal agents. He complained of persistent dysphagia beginning at age 7 years. Esophageal stricture and multiple whitish patches were observed by endoscopy and endoscopic biopsy revealed numerous fungal hyphae consistent with candida esophagitis. He received esophageal balloon dilatation four times, and his symptoms improved.

Paraquat와 bentazone이 횐쥐의 간조직과 NIH 3T3 섬유모세포에 미치는 독성과 그 독성에 대한 3-MC의 보상효과를 조사하기 위하여 NIH 373 섬유모세포에 적응한 후 경시적으로 MTT분석을 이용하여 세포독성을 측정하고 Sprague Dawley계 웅성 횐쥐에 paraquat와 bentazone단독 및 paraquat 및 bentazone과 3-MC를 병용투여한 후 경시적으로 관찰한 결과 paraquat와 bentazone은 NIH 3T3 섬유모세포에 대하여 $IC_{50}$값이 각각 1668.97 ${\mu}M$, 1506.97 ${\mu}M$으로 Borenfreund의 독성평가기준에 의하면 저독성이었다. Paraquat와 bentazone 단독투여군의 H&E 염색에서 3시간째에는 문맥 주위 세포들이 변성을 일으키고 별모양 세포들이 증가하였으나 12시간째에는 간소엽 전체의 세포들이 변성을 일으켰으며 48시간째에는 더욱 심한 변성이 일어났다. 특히 bentazone 투여 후 48시간째에는 핵농축현상이 뚜렷하였다. Best carmine 염색에서 glycogen 과립을 함유하는 간세포들도 3시간째에는 문맥주위의 세포들이, 12시간째에는 간소엽 전체의 간세포들이, 48시간째에는 전체의 간세포들이 함유하는 glycogen 과립량이 현저히 증가하였다. 3-MC를 paraquat와 bentazone과 동시에 투여한 군에서 3시간째와 12시간째에는 단독투여군과 유사하였으나 48시간째에는 bentazone과 3-MC 동시투여군의 문맥주위의 간세포들이 재생되는 경향이었으며 paraquat와 3-MC를 동시에 투여한 군에서는 중심정맥 주위의 세포들만이 glycogen과립을 함유하고 있어 단독 투여군과 뚜렷한 차이를 관찰할 수 있었다. 이 결론에서 3-MC는 paraquat와 bentazone에 의한 간세포의 독성을 경감시킬 수 있는 물질임을 알 수 있었다.

당뇨병 환자에서 간비대와 간 기능 이상이 동반될 경우 간 내 당원축적증과 비알콜성 지방간염을 감별해야 한다. 저자들은 인슐린 치료를 제대로 받지 않아 혈당 조절이 불량한 환자에서 저혈당과 간비대로 발현한 간 내 당원축적증을 경험하여 보고한다. 만 6세경 1형 당뇨병으로 진단받은 환아로 10세경 우상복부 통증과 반복되는 고혈당과 저혈당으로 내원하였으며, 당시 진찰상 둥근 얼굴, 우측 늑골연 하방 6 cm 정도에서 만져지는 간비대가 있었다. 검사상 소변 케톤 양성, 당화혈색소는 9.6%였다. 간 효소치가 증가되어 있었고, 혈중 콜레스테롤/중성지방 250/267 mg/dL였다. 바이러스성 간염, 자가면역성 간염, 대사성 간 질환에 대한 검사는 모두 정상이었다. 복부 초음파 및 컴퓨터 단층 촬영상 지방간과 간비대 소견을 보였다. 간 조직 검사상 PAS 염색에서 양성, diastase-PAS 염색에서는 음성으로 전형적인 당원축적증의 소견을 보였다. 고혈당을 보일 때마다 초속효성 인슐린을 투여하고 심한 저혈당의 증상이 동반된 경우 글루카곤을 투여하였으며 생옥수수 전분 가루를 간식으로 먹이면서 저혈당 횟수가 감소하여 퇴원하였다. 현재 외래에서 초속효성 인슐린으로 혈당 조절하면서 관찰 중이다. 제1형 당뇨병 환자에서 당원축적증은 간비대와 간 효소치의 상승을 야기할 수 있는 원인이다. 본 증례에서는 심한 저혈당이 반복되어 하루에도 수 차례 글루카곤을 투여하였으며, 생옥수수 전분 가루을 투여하면서 저혈당이 호전되었다. 엄격한 혈당 관리로 간 비대 및 간 기능 이상이 호전될 수 있으므로 적절한 인슐린 치료로 혈당을 조절하고 저혈당을 예방해야 하겠다.

In order to know the effects of Calculus $Bovis{\cdot}F디$ Ursi aqua-acupuncture ($C{\cdot}F$ aqua-acupuncture) to the liver damage, we carried out the treatment of $C{\cdot}F$ aqua-acupuncture and injection of Kam-Du-Tang on the liver damaged rat which is induced by aconitine, and then ultrastructural study has been to the liver tissue. The results were as follows: 1. In the hepatic cell of normal group, the nuclear envelope is round and electro-density of nucleoplasm is relatively low, and have one or two large nucleolus. Cell organelle is developed rough endoplasmic reticulum(RER) and many mitochondria, glycogen granules, smooth endoplasmic reticulum(SER) and Golgi apparatus. 2. In 24 hours control group, nuclear envelope is very irregular, RER and most of cell organell is shown that destroyed by aconitine. This is similar to the 48 hours control group. In 72 hours control group, RER is recovered somewhat but cristae of mitochondria is not seen the shape 3.In 24 hours $C{\cdot}F$ aqua-acupuncture group, nuclear envelope is very irregular and cristernae is very dilatable and many mitochondria is dilationed and the cristae is not definite like the control group. In 48 hours $C{\cdot}F$ aqua-acupuncture group, nuclear envelope is relatively round and chromatin is regular. Cristernae of RER and ribosme is somewhat imperfect but is similar the normal group, and the cristae of mitchondria is shown definitely like the normal group. In 72 hours $C{\cdot}F$ aqua-acupuncture group, nuclear envelope is round and cell organell is similar to normal group. 4. In 24 hours Kam-Du-Tang group, nuclear envlope is very irregular and cell organelles are destroyed by the effects of aconitine. In 48 hours Kam-Du-Tang group, nuclear envelope is somewhat irregular but chromatin is relatively regular. RER is seperated regularly through the cytoplasm, but cannot make the structure of lamina, and cistennae is very dilationed. many of glycogen granules is seperated regularly. In 72 hours Kam-Du-Tang group, RER makes the lamina. Mitochondria is a little but inner space is dilationed so the shape of is not definite and a lot of glycogen granules are accumulated in several places. It see the above result, hepatic cell that is damaged by aconitine is effected chiefly by the $C{\cdot}F$ acupuncture and effect of acupuncture is similar to the detoxicated effect of Kam-Du-Tang.

The present study was designed to estimate the protective effect of (-) epigallocatechin gallate (EGCG) on ethanol-induced liver injury in rats. Chronic ethanol administration (6 g/kg/day ${\times}$ 60 days) caused liver damage that was manifested by the elevation of markers of liver dysfunction - aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, bilirubin and ${\gamma}$-glutamyl transferase in plasma and reduction in liver glycogen. The activities of alcohol metabolizing enzymes such as alcohol dehydrogenase and aldehyde dehydrogenase were found to be altered in alcohol-treated group. Ethanol administration resulted in the induction of cytochrome p450 and cytochrome-$b_{5}$ activities and reduction of cytochrome-c reductase and glutathione-S-transferase, a phase II drug metabolizing enzyme. Further, ethanol reduced the viability of isolated hepatocytes (ex vivo) as assessed by trypan blue exclusion test and induced hepatocyte apoptosis as assessed by propidium iodide staining. Treatment of alcoholic rats with EGCG restored the levels of markers of liver injury and mitigated the alterations in alcohol metabolizing and drug metabolizing enzymes and cyt-c-reductase. Increased hepatocyte viability and reduced apoptotic nuclei were observed in alcohol + EGCG-treated rats. These findings suggest that EGCG acts as a hepatoprotective agent against alcoholic liver injury.

The purpose of this study was to examine the effects of long- term Ginseng administration on metabolism of rats during growing period. A group of pregnant rats was divided into 2 groups, the one was given 18% casein diet and the other, 18% casein diet with ginseng powder 500 mg/kg body was during the gestation and lactation. After weaning, 84 male offsprings were taken at random from the 2 groups. The rats from each group were divided subsequently into 2 groups. Ginseng and control group. The rats were sacrificed at three different times -7, 11, 17 weeks of age. The body weight and amount of food intake were measared during the feeding period. After sacrificing, the weight of some organs, liver glycogen. serum total lipid values, urinary nitrogen and creatinine were examined. The results were analysed by t-test and F-test Results obtained are summarized as follows : 1) Addition of Ginseng did not significantly affect the body weight of rats. 2) The weight of liver, testis, epididymal fat pad were not significantly different between ginseng group and control group during the experimental period. 3) Urinary nitrogen and creatinine did not have significance among all the experimental groups. 4) Amount of liver glycogen was not statistically significant in the ginseng group and control group. 5) The serum total lipid values of rats Iron ginseng group was not statistically different from that of the control group. It can be concluded that Ginseng, 500 mg ginseng powder /kg body wt, does not affect the metabolism of rats under the conditions of this study.

The toxicity of purified ricln from Ricinus communis to rats was examined by histological and histochemical methods. Sprague-Dawley rats were injected intraperitoneally with 75$\mu\textrm{g}$/kg body weight of ricin and were sacrified at itntervals of 6, 24, 48 and 120 hours after injectoon. The major morphological changes, such as cloudy swelling, hydropic degeneration, necrosis, fatty change, blood congestion, increase of Kupffer cells in number and extension of sinusoids, were obvious in the liver of experimental group. These morphological changes of hepatic cells were mainly observed in both the periportal and midlobular region of hepatic lobule. The extension of sinusoids was obvious in the controlobular region. And glycogen dlstrlbution of hepatic cells tended to decrease in the same region showing morphlogical changes as compared with the control group.
